Problems solved by technology

[0004] Related antistatic fluids have high requirements on humidity. If the humidity is too low (less than 15% RH), the antistatic fluid will become unstable, and the surface resistance will increase significantly, reducing the antistatic effect.

Embodiment 1

[0053] A preparation method of stable antistatic liquid:

[0054] S1. Mix 4.5kg SIPU-8633 water-based polyurethane emulsion, 4kg isopropanol, 1kg poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonic acid), 0.2kg DMPA-based HDI type water-based polyurethane dispersion and 0.12kg B-83 type defoamer were added into the explosion-proof high-speed disperser, the stirring speed was 1200r / min, and the stirring time was 3h to obtain the premix.

[0055] S2. Add 0.08kg AMP-95 film-forming aid to the premixed solution, continue to stir and disperse for 1 hour, and the stirring rate is 1200r / min to obtain the base solution;

[0056] S3. Add 0.1kg of aziridine curing agent to the base liquid before coating the article, stir and disperse for 0.2h at a stirring rate of 1200r / min to obtain an antistatic liquid, which can be used for coating at this time.

Embodiment 2～ Embodiment 4

[0058] The difference between embodiment 1, embodiment 2, embodiment 3 and embodiment 4 is shown in table 1.

Abstract

The invention relates to the field of anti-static packaging, and particularly discloses stable anti-static liquid and a preparation method thereof. The stable anti-static liquid is prepared from the following raw materials by weight: 40-45% of a waterborne polyurethane emulsion; 40-45% of a diluent; 10-15% of polythiophene; 2-5% of a waterborne polyurethane dispersion; 0.8-2% of a film forming agent; 0.8-1.5% of a defoaming agent; and 0.8-1.2% of a curing agent. The preparation method comprises the following steps of: S1, stirring and dispersing the waterborne polyurethane emulsion, the diluent, the polythiophene, the waterborne polyurethane dispersion and the defoaming agent to obtain a premixed solution; S2, adding the film forming agent into the premixed solution, and stirring and dispersing to obtain a basic solution; and S3, adding the curing agent into the basic solution, and stirring and dispersing to obtain the anti-static liquid. The stable anti-static liquid has the advantages that the stability and the anti-static effect of the anti-static liquid are improved.

Description

technical field [0001] The application relates to the field of antistatic packaging, more specifically, it relates to a stable antistatic liquid and a preparation method thereof. Background technique [0002] On the surface of some daily necessities or industrial products, there is often static electricity, which will generate static electricity interference, and absorb the dust in the air to the surface of the article, affecting the quality of production and life. Therefore, anti-static treatment is carried out for products and packaging. [0003] Anti-static treatment is generally coated with anti-static liquid. After the anti-static liquid is applied to the surface of the object, a very thin transparent film is formed to provide a durable and efficient static dissipation function, which can effectively eliminate the accumulation of static electricity generated by friction and reduce static interference and dust. Adhesion phenomenon, antistatic fluid is indispensable for p...
